well, you got error when switching from Gpad ROM to Lonpad ROM?
did you reboot after lk.rom flashed and flash other files on 2nd FWDN boot?
Good luck with that. The furthest I got with lonpad's lk.rom and Coby's update.zip was the NAND size was always wrong. Coby's update.zip installed ok and the tablet booted up, but it detected a blank nand, and I couldn't mount it. I created a 4g nand image, but FWDN misreports it as 2.8g. I think there is something wrong with lonpad's bootloader (lk.rom) and 4g nand support.
